Roofs and siding are low-pressure jobs. High pressure strips shingle granules, forces water behind vinyl, and voids roofing warranties. The professional method is soft washing: applying a cleaning solution at low pressure and letting chemistry kill the algae and mildew. This collection has everything for safe exterior house washing: dedicated soft wash systems, second-story nozzle kits that reach 30+ feet from the ground, heavy-duty telescoping wands up to 24 feet, gutter cleaning attachments, and the chemical injectors and sprayers that put solution where you need it.
